Add support for retrieving the EXT4 environment from an NVME device, the
same way it can be retrieved from MMC, SCSI, or VIRTIO.

To use the EXT4 environment from an NVME device, pass
CONFIG_ENV_EXT4_INTERFACE="nvme" in the defconfig.

As part of bringing the master branch back in to next, we need to allow
for all of these changes to exist here.

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.

This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing
changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

Specifying a file in an EXT4 or FAT partition on a virtio device as
environment location failed because virtio hadn't been initialized by
the time the environment was loaded. This patch mirrors commit
54ee5ae84191 ("Add SCSI scan for ENV in EXT4 or FAT") in issue and
fix, just for a different kind of block device.

The additional include in include/virtio.h is needed so all functions
called there are defined, the alternative would have been to include
dm/device.h separately in the env/ sources.

Checkpatch suggests using "if (IS_ENABLED(CONFIG...))" instead of
"#if defined(CONFIG_...)", I'm sticking to the style of the existing
code here.

Remove <common.h> from all "env/" files and when needed add
missing include files directly.

The part_length parameter is not used. Remove it.

When having environment stored in EXT4 or FAT
and using an AHCI or SCSI device / partition
the scan would not be performed early enough
and hence the device would not be recognized.
This change adds the scan when the interface
is "scsi" in a similar way to mmc_initialize.

Add ENV_ERASE_PTR macro to handle erase opts and remove the associated
ifdef.

This patch is a extension of previous commit 82b2f4135719 ("env_internal.h:
add alternative ENV_SAVE_PTR macro").

Move this out of the common header and include it only where needed.  In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly.   Finally, we have a few
cases where we did not need to include <asm/global_data.h> at all, so
remove that include.

This parallels what I added for FAT in commit 6731bef6966, allowing the
environment to be found in a specific partition on the device that the
board's mmc_get_env_dev() returns. On the Banana Pi R2 that means the
device that U-Boot was loaded from; either the internal eMMC or an SD
card.
